An auxiliary fixation device for arterial vascular anastomosis

Abstract

The invention discloses an auxiliary fixing device for arterial blood vessel anastomosis, comprising a fixing plate, a sliding groove, a clamping groove, an escape hole, a fixing seat, an escape groove, a fixing shaft, a limit handle, a T-shaped slider, a spring, a polygon Limiting plates and clips, first of all, through the design of the double-group clamping arterial clip fixation structure, it is convenient for the surgeon to clamp the arterial clips on both sides of the arterial cut end, and the fixation of the arterial clips on both sides of the arterial cut end is realized effectively. The problem of free movement of the arterial clip during anastomosis is prevented. Secondly, through the cooperation effect of the left and right sliding size adjustment device, the in-depth distance of the arterial clip can be easily controlled according to needs, which improves the convenience of clinical operation. The function of the angle regulating device can also change its angle, which ultimately greatly improves the convenience and stability of the arterial anastomosis process, and is beneficial to the popularization and application of surgery.

Description

technical field [0001] The invention relates to an auxiliary fixation device for a blood vessel clip, in particular to an auxiliary fixation device for anastomosis of arterial blood vessels. Background technique [0002] At present, when performing end-to-end anastomosis for small and medium-diameter arteries, it is necessary to use vascular clips to block the arterial blood flow at the broken ends of the blood vessels on both sides, and then manually fix the longitudinal position and distance of the blood vessels on both sides by the surgeon. The anastomosis can only be performed after the broken ends are well aligned. During the above-mentioned surgical operations, due to the lack of effective fixation of the rear end of the existing arterial vascular clip, the surgeon usually uses sterile gauze to hold it, but this not only requires repeated Adjusting the position of the arterial clip, more importantly, the fixation effect is poor, and it is impossible to achieve synchron...
